Given numbers are 780, 124, 258, 525

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 124 are 2 x 2 x 31

Prime factors of 258 are 2 x 3 x 43

Prime factors of 525 are 3 x 5 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 780, 124, 258, 525

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(780, 124) = 24180

GCD(780, 124) = ( 780 x 124 ) / 24180

= 780 / 124

= 780

Step2:

LCM(4, 258) = 516

GCD(4, 258) = ( 4 x 258 ) / 516

= 4 / 258

= 4

Step3:

LCM(2, 525) = 1050

GCD(2, 525) = ( 2 x 525 ) / 1050

= 2 / 525

= 2

So, Greatest Common Divisor of 780, 124, 258, 525 is 1
